I think "Never forever" has to do with things that do not last forever. Your beliefs, your hopes and your personal relationships. And the world is so complex and amazing, that we'll never understand it, and throughout our lives we'll learn and never know anything clearly. We can't live and learn fully because of the bad light = "all that sun" = the worlds beauty. This of course only holds, if you are convinced that "bad light" is an ironic metaphor that isn't negative at all.
